Features
The performance pressure seal cover swing check valves
Pressure seal bonnet swing check valves have the same application features as bolted bonnet valves shown on this page.The major difference is that the bonnet is designed for high-pressure, high-temperature service.
Swing check valves are best suited for moderate velocity applications. Either too low or too high a velocity can seriously damage the valve's internals. Valve damage can also be caused by rapid and frequent flow reversals, pulsations or execessive turbulence.
Swing check valves sre designed for intallation in horizontal lines. They may also be used in vertical lines when the flow is upward under the disc.
DONG-A VALVE cast steel pressure seal valves comply with the design and test requirements of ASME B16.34 and the installation dimensions of ASME B16.10.
All DONG-A VALVE pressure seal swing check valves have the feature shown below. They are engineered to provide convenience, durability and maintainability.
